Notable Changes from 2024
The 2025 Sierra HD features significant upgrades over its predecessor.

Enhanced trailering technologies, including available Transparent Trailer View and adaptive cruise control with trailering, make towing easier and safer.
Infotainment and Technology Features
The 2025 GMC Sierra HD truck delivers cutting-edge technology. The Denali Ultimate trim offers a best-in-class 15-inch head-up display, displaying vital information like speed, navigation, and trailering details directly onto the windshield.
Standard technology on base models includes:
- 13.4-inch infotainment touchscreen with customizable apps.
- Wireless Apple CarPlay and Android Auto integration.
- 12-speaker Bose audio system (available on higher trims).
